Establishing a baseline is a critical step in a single-case experimental design as it provides the basis for comparison with subsequent measures. Therefore, the first measure taken from the subject is typically for the purpose of establishing baseline.

Option B is not always true as changes in the measure may sometimes occur due to factors other than the intervention.

Option C is incorrect as single-case experimental designs are not considered quasi-experimental designs.

Option D is incorrect as single-case experimental designs can be repeated in more than one subject, although each subject serves as his or her own control.
